Offset

The layback provides some offset.That post provides the same offset as this one.Do I need a bigger frame too?

The frame is an XL and I have long legs (I'm 6'6") I always end up ramming the seat back as far as I can to get the right position over the pedals. I kinda took a chance since I hadn't ridden one, hopefully it'll work out.

I use 'em. I like the looks of a set back better'n a straight post personally. Just old school I guess. You'd freak out at my 24" tt and 140mm stem too. I just like my bikes that way.

I think sometimes people think an offset seatpost is used to lengthen the frame rather than position a rider correctly over the pedals. My old I.F. had a 24tt and a 140 stem. This long tt short stem thing is new to me.

Why does frame size have anything to do with post offset? I'm my mind post offset is all about seat tube angle and desired position over BB spindle. The Niner (like many 29" bikes) has a pretty steep STA. I have a strait post on my Niner but I also run a 100mm fork and my saddle is still way back on the clamp. In comparison my road bike has a 1 deg. slacker STA a Moots Lay-back post that clamps the saddle near the rear of its rails. Whenever I build a bike I set my seat height at my dimension (31.25: c-t) and then drop a plumb off the nose of the saddle and make sure I am 7.5 cm back. All my bikes measure out exactly the same except the DH bike.

That is exactly how I measure up my bikes. Height, fore-aft, then cockpit length. Good to see others use this method too....I think it's the best way to go about it.

My body's about the same dimensions as yours, and I have the same bike. I bought a Thomson straight post and was not happy. Went with a Salsa post that has a bit of set back (no silver Thomson set back in our size) and it's just right. I should have done some pre-purchase measuring. Oh well.

hehe, some people are SO scientific about that measurement. Me? I center the saddle on the post(more or less), and put the hieght at my hip socket or a titch higher. Its a mountain bike. I move around so much that exact seat placement isn't gonna matter one iota. I'm a little more particular with the 'cross bike, but not much. So long as the reach feels good, and the leg extension feels right, I'm good to go.

Hey evil,

I measured off my road bike to get a good idea for stem length and got a 110mm 10 degree X4. I take it a 110 felt too short? Hopefully I'll be fine, I have a short torso. What bar do you run?
